Installer information
Trenton Co-Axial Venting Chart
Note: The vent must not exceed
a total length of 30 feet. Any
combination of rise and run may
be used but must be constrained
to the boundaries of this chart. A
Maximum of three (3) 90° elbows
may be used. Only one (1) 90°
elbow or combination of other
elbows equaling 90° can be used
without reducing horizontal run.
For each additional 90° elbow, or
an equal combination of elbows,
reduce horizontal vent run by 2
feet. Ensure vent pipe is properly
supported.
Damper Note:
The damper position is factory
set to the closed position. Every
venting configuration is different,
and the damper setting may need
slight adjustment.
(See page 33 for damper
adjustment).
